This one isn't hard to do, and again doesn't require any special tools. Everything should run you about $50
Step 1: Gather the Materials
Clear Spray Lacquer
4" ABS pipe (2' segment)
4" end caps (2)
3/8" vinyl tubing
ABS pipe cement
Saw (handsaw, bandsaw, jigsaw, or miter saw)
Step 2: Disassemble the Fountain
Flip over the fountain. Along the bottom are circular bumps. Drill through each one with room to spare. If this does not loosen it, you will have to cut the two halves apart. Your reward for this arduous task will be a pump and two solar panels.
This was the by far the hardest step!
